Question:
Why are alkynes generally considered to be less reactive than alkenes?


Replies:
I am not sure that this generalization is "general". For example ethyne(acetylene) is more reactive with respect to oxygen than is ethene(ethylene). I think that this reactivity difference is attributed to the fact that a carbon-carbon triple bond is stronger than a carbon-carbon double bond -- 812 and 615 k joule/mol, respectively.
